OpenTofu is growing up fast! Born when Terraform shifted to a Business Source License (BSL) in August 2023, this community-driven open-source fork of Terraform has matured into a powerful, production-ready, infrastructure-as-code tool in under five months.
A lot has happened in that time, so let’s recap the milestones and remind you of the benefits of switching to OpenTofu. We will also explain how to install OpenTofu and provide some valuable resources for making the most of this drop-in replacement for Terraform.
OpenTofu (formerly OpenTF) began life as a fork of Terraform after Hashicorp announced in August 2023 that it was adopting a BSL for Terraform, which had always been open source. Support for the initiative was massive and immediate, with the OpenTofu manifesto garnering 30,000 GitHub stars by the end of August. In September, OpenTofu joined the Linux Foundation, ensuring the tool would remain neutrally housed with impartial governance and community oversight. Alpha and beta versions soon followed, with the first stable release candidate coming out in December 2023.
OpenTofu is supported by more than 150 companies, four of whom have committed to covering the cost of FTEs to work on the project, Spacelift is one of those companies, and we are members of the project’s steering committee, together with representatives from Scalr, Gruntwork, Harness, and env0. Hundreds of individuals also support OpenTofu, inspired by its simple mission of keeping Terraform open-source always.
OpenTofu is a logical choice for anyone switching from Terraform or adopting the infrastructure-as-code (IaC) approach for the first time. Its benefits include:
- Stability: OpenTofu is a member of the Linux Foundation, which not only ensures input from a large community of open-source experts, practitioners, and users, but also provides peace of mind that OpenTofu will remain stable and continue to grow and improve.
- Community support: The endorsement of so many companies and individuals provides strong community-driven backing. This community will drive OpenTofu in the right direction, guided by impartial governance and oversight.
- Dynamic project: As an open-source, community-driven initiative, OpenTofu offers exciting potential for contributors to make a real difference. This will help the project grow and adapt in line with users’ needs.
Starting with OpenTofu involves a few key steps:
- Installation: Install OpenTofu using the method appropriate to your operating system.
- Configuration: After installing OpenTofu, you can use it as it is, but you can also configure it to suit your specific needs. This might include setting up user preferences or installing and configuring other tools that may integrate with your OpenTofu repositories.
